watchout guys. On line auto sport sent me the wrong exhaust for my nov even tho i gave them the part number from there web site. Site shows they sell sportex manifold for nova gte/gsi 4 branches going into 2 then 1 at around 159 quid. What the dont say is its the sr one you get 4 into 1 which really cost 120 odds. Real cheap n nasty gear that not even a fart could flow out of. The guy then takes a serious memory problem, claims he's rite then charges for handling then bumps you for the postage. Forgot say he stalls your refund. Anyone had this prob with them?
